1260-3SMG-400

1260-3SMG-400 is a 1260 series AC hybrid surge protective device designed to protect high-risk electrical service entrance and branch panels. Based on its advanced hybrid architecture (MOV + GDT technology), this series can provide excellent reliability and safety protection due to no leakage or follow current. This surge protective device is intended to be installed at the front end of the installation, in the main switchboard, close to sensitive terminals or in installations without LPS (lightning rods). Typical applications include electrical service entrance, branch panels, all power circuits, heavy industrial and EV charging stations.
